PORTLAND, Ore. - Marchers made their way through downtown Portland on Tuesday as part of a larger worldwide protest called the Million Mask March.
The march was organized by Anonymous, a hacktivist group notorious for a well-publicized series of hack attacks on government, religious and corporate websites. Anonymous has been around for a decade.
Portland's participation in the worldwide effort was small, but police were on hand to keep the peace. At one point, officers got in a scuffle with some of the marchers. KATU's Jet Ranger 2 was flying overhead at the time and caught the incident on camera.
Police made two arrests for blocking traffic. They said the event was otherwise peaceful.
The march coincides with England's Guy Fawkes Day and the demonstrators were advocating for a range of issues. The group generally protests against corrupt governments and corporations.
